Hello Eli,

Looks like this "stab-in-the-dark" fix was pretty good; haven't noticed any
crash in the last 3 days.

So I am closing this issue. If I see a crash, I'll open a new issue for
that.

Thanks!

[Message part 6 (text/plain, inline)]

Hello,

In the past one-two weeks, I have been noticing arbitrary crashes when
working in Org mode, with other packages like org-tree-slide and
artist-mode. My guess is that this has to do with packages dealing with
overlays.

I do not have a reproducible recipe, but this time, I got the full
backtrace (attached as gdb.txt).

The log shows the the beacon package caused this. For reference, here is
the source of beacon.el:
